BED-SPRING rleiirnnnn.

Specification of Letters Patent. 7

Application filed February 20, 1914. Serial No. 820,024.

To all whom it may concern:

Be it known that I, WILLIAM G. Luce, a citizen of Canada, residing at Winnipeg, in the Province of Manitoba and Dominion of Canada, have invented new and useful Improvements in Bed-Spring Tighteners, of which the following is a specification.

This invention relates to improvements in bed spring tighteners and especially with reference to the provision of a frame of an improved construction and to which the ends of a spring bed bottom or fabric are attached and by means of which the bed bottom may be tightened or adjusted from time to time to take up slack and prevent the bed bottom from sagging.

The invention consists in the construction, combination and arrangement of devices hereinafter described and claimed.

In the accompanying drawings :Figure 1 is a plan of a bed spring or bed bottom provided with a frame and tightening devices constructed in accordance with my in- Fig. 2 is a transverse sectional view of the same. Fig. 3 is a vertical longitudinal sectional view of the same. Fig. 4': is a detail sectional view of the same on a larger scale. Fig. 5 is a similar view.

' bottom may be of any suitable construction within the scope of my invention.

The bar 1 is provided near its ends with downwardly extending plates or arms 4 each of which is formed, on its inner side, with a cylindrical cup 5 which is internally screw threaded as at 6. Each plate or arm 4i also has on its inner side a socket 7 concentric with the cup and with a centrally arranged opening 8.

The bar 2 is provided on its inner side near its ends with downwardly extending arms or plates 9 each of which has athreaded stud 10 near its inner side.

The sides of the frame are formed by a pair of longitudinally arranged tubular members 11 each of which is threaded at of each tubular member 11 is a thickened diametrically reduced portion 12 which is threaded and which is engaged by threads of an adjusting bolt 13. Each of these bolts is provided near its outer end with an annular collar 14 which has a bearing in one of the sockets 7 so that the said bolts bear against the arms a of the bar 1 and are also connected thereto for turning movement. The outer end of each bolt is angular in form as at 15 and thereby adapted to be engaged by a suitable wrench sothat the bolts may be turned and by coaction. with the tubular members 11 in which they are threaded adjust the bed frame longitudinally so as to take up slack in the bed bottom as will be understood. In order to strengthen the tubular members 11 I also provide inner tubular members 16 which are shorter than the members 11 are arranged therein at the same end with the bolts 13 and are engaged with the central threads 6 of the cups 5 and thereby connected to the cross bar 1. g

It. will be readily understood that the stretcheror tightener frame of the bed bottom may be readily assembled and disas-' guide and centering cup and a stud, in com-' bination with a tubular side member secured to said stud and slidably engaged with said guide and centering cup and an adjusting screw mounted for rotation in a bearing in said cup and having threaded engagement with said tubular side member, the said cup being provided with a socket and said adjusting screw having an annular collar mounted in said socket.

2. A bed spring tightener comprising bars for connection to the ends of a spring bed bottom and provided respectively with a guide and centering cup and a stud, in combination with a tubular side member secured to said stud and slidably engagedwith said guide and centering cup and an ad- Patented Nov. 3, 1914. l

having threaded en side of said cup.

In testimony whereof I affix my signature in presence'of two Witnesses.
